I'm in the process of changing my ring and pinion from 3.55 to 4.10 and it seems the previous owner lost the bolt to the pinion shaft and drove a spring pin in there instead. I can't get the thing out. Any tips for me? I can't drill it. And tried to tap it out from the other side and just bent the stuff small enough to fit in there.

Pinion shaft?? Do you mean the carrier?

Basically you have few options. Get a proper drive punch (not a cheapo) or a solid carbide bit (not carbide tipped and not cheapo) and drill it out. Since you're going to 4.10's the carrier is being replaced anyway.

Poor people problems. Lol. I got my answer from someone in the yj section. The rear brake is 3.55 and up. Front Dana 30 is 3.73 and up. So the front carrier will be the one needing the carrier. The spring pin is also a common hack job fix I guess. So back to the hammer when I get a little free time again. The jeep is an 89 yj 4.2 with an ax15. For others needing the info.

Not a hack job. Use of a roll pin instead of a threaded bolt to secure the cross pin is a stock arrangement.
